Testing the "overlay" filesystem

Overlay filesystems

Todo: have some fun with / test:

• http://romanrm.ru/en/mhddfs
• https://www.nowhere.dk/articles/fuse-coolness-with-mhddfs

Example of three combined volumes:

$ df -h
Filesystem            Size  Used Avail Use% Mounted on
...
/dev/sda1              80G   50G   30G  63% /mnt/hdd1
/dev/sdb1              40G   35G    5G  88% /mnt/hdd2
/dev/sdc1              60G   10G   50G  17% /mnt/hdd3
mhddfs                180G   95G   85G  53% /mnt/virtual

This looks really cool, I really need to test this in my mini testlab!
